Segmented Indirect Versus Direct Bracket Bonding

This randomized clinical trial compared two methods of attaching orthodontic brackets to teeth: conventional direct bonding, in which each bracket is placed and bonded individually in the mouth, and a segmented modified indirect bonding technique, in which brackets are first positioned on a plaster model of the patient's teeth and then transferred to the mouth in segments using a hot-glue transfer tray. The purpose was to find out whether the two techniques differ in how often brackets come loose (bond failure) during treatment. Eighteen patients receiving fixed orthodontic appliances at Riyadh Elm University, Riyadh, Saudi Arabia, were randomly assigned so that their brackets were placed by either the direct or the modified indirect technique. The same bracket type and adhesive were used in both groups. Patients were examined every four weeks for six months, and any bracket that debonded was recorded along with the tooth involved, the arch (upper or lower), the side (right or left), and the time from bonding to failure. The main outcome was the time from bonding to bracket failure; the investigators also compared failure rates and examined whether failure varied by tooth type, arch, or side.

Digital Bonding vs. Direct Bonding Study

This is a prospective, 2-armed, randomized, multi-site clinical study to demonstrate that digital bonding is a more efficient treatment method than direct placement of brackets.

Comparative Outcomes of Damon Ultima vs Pitts 21 Pro Bracket Systems

Title Comparative Evaluation of Treatment Outcomes between Damon Ultima and Pitts 21 Pro Bracket Systems; A Randomized Clinical Trial Abstract Background: The primary advantages of self-ligation brackets include faster archwire removal and ligation, reduced or eliminated need for chairside assistance, secure archwire engagement, and lower bracket-archwire friction, which collectively contribute to a substantial reduction in resistance to sliding and are theorized to enhance the efficiency of initial tooth alignment. This randomized controlled trial (RCT) will be conducted to assess differences in treatment outcomes with these two different self-ligation bracket systems. Subjects/Materials and Methods: This randomized clinical trial included 40 participants with full permanent dentition (excluding third molars) exhibiting Angle Class I malocclusion with moderate crowding. Patients who were scheduled to undergo orthodontic treatment were allocated into two groups: Damon Ultima and Pitts 21 Pro. The total treatment duration will be measured in months from the bonding day to the completion of treatment, in addition to the number of visits. Pre-treatment, post-alignment, and post-treatment records were obtained, including intraoral scans (IOS) for assessing alignment efficiency and arch parameters. Periapical radiographs of the upper and lower incisors were taken before and after treatment to measure the amount of root resorption. Treatment outcomes were evaluated using the American Board of Orthodontics (ABO) grading system. Additionally, pain perception and patient treatment perception were assessed.

Erbium-doped Yttrium Aluminum Garnet (Er:YAG) Laser vs Conventional Ceramic Bracket Debonding: A Split-Mouth Clinical Trial

This randomized split-mouth clinical trial evaluates enamel surface preservation, pulpal temperature variation, and patient-reported discomfort during ceramic orthodontic bracket removal using two Erbium-doped yttrium aluminum garnet (Er:YAG) laser parameter settings compared to conventional mechanical debonding. Pulpal temperature is monitored in real time using a thermocouple device. Enamel integrity is assessed using the Adhesive Remnant Index (ARI) under 40× magnification. The study aims to determine optimal laser parameters ensuring safe and conservative bracket removal.

Damon vs MBT Braces: Patient Compliance and Treatment Efficiency

Comparison between two bracket prescription systems, MBT and DAMON Ultima brackets and evaluate whether the changes incorporated in DAMON Ultima brackets can drive earlier improvement on teeth position, clinically visual progression of treatment, during initial stage of treatment. Another aim of this study is the effect of chosen bracket system on patient compliance.
